METAL WINDOW CONSTRUCTION.

' 'Application filed July 16, 1925. Seal No. 43,902.

relates to metal Windows. The principal objects ofthe present invention are to produce a strong, rigid, lightweight metal window of simple construction and pleasing appearance which can be cheaply manufactured; to reduce the number of parts of the Window, and to provide for the easy assemblage ofv these parts to form window casing and sashes of accurate dimensions and of such cross-sectional shape that they will readily accommodate metal weather strips and render easy the application of such strips thereto; to utilize parts of the same cross-sectional shape and dimen- This invention sions for most of the framing members of the windows of different types; and to provide members adapted to serve as combined r Window stops and screen supports for said windows.

The invention metal window constructions hereinafter shown and, described; and it also consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings which form like symbols refer to like parts wherever they occur, f

Fig. 7 is a vertical section through a double easement window;

' Fig. 8 is a horizontal section through one side of said window on the line 8-8 in Fig.A

7; and

consists principally in thepart of this specification and wherein is a fragmentary side view of one Fig. 9 is a horizontal section through the ranged for vertically sliding upper andv lower sashes B and B1, respectively, Wooden parting strips C and metal inside and outside stops or mouldings D. The window casmg or frame A is made up of one-piece metal side, head and sill members. The side and top members 10 are of the same crosssectional shape and size, each of said members comprising side marginal flanges 11 connected by a Web portion 12. The web portions of the framing members 10 are provided with grooves or channels 13, which extend longitudinally from end to end thereof and are adapted to receive the parting beads or strips C.

The end faces of the side marginal flanges 11 of the framing members 10 are provided with undercut grooves 13 which extend longitudinally of said flanges from end to end thereof; and the webs of said members are provided at their middle portions With undercut ribs 14 which are disposed on the flanged side of said web and extend from end to end thereof. 4Doubly-channeled sash weight boxes 15 have'side marginal flanges 16 provided with undercut ribs 417 adapted to slidably engage the undercut grooves 13 in the framing members 10 that form the jamb members of the window casing; and the Webs 18, which separate the two channels, are formed with undercut grooves 19 adapted to slidably engage the undercut ribs 14 on said jamb members. By this arrangement, the members 10 and 15 can be readily assembled to form completely Venclosed boxes for the sash weights and pulleys. The members 15 -are preferably made from a single piece of sheet met-al which is longitudinally folded to the shape desired.

The top and side framing members 10 of the window casing A are also provided at their inner and outer corners with rectangular recesses or rabbets 19 adapted tol receive the `inside and outside stops or mouldings D which are removably secured in position by means of screws20. The bottom frame or sill member 20 f the Window casing A is of slightly dierent cross-sectional shape, said member comprising a sloping web portion,

adepending 'outer marginal flange and an upstanding rib rportion adjacent. to the ends theA form of-metal strips of substantially H- v strip faces the deep channel shaped cross-section; that is, eac-h strip is provided on each side with a channel, either' one of which is adapted to serve as a slide for awindow screen (not shown). As shown in the drawing, one channel 23 of the strip. is .of greater-depth than the other channel 24 thereof; andl the strips forming the slideways for the screen are preferably arranged so that t-he shallow channel of one of the opposite strip. As the width of the screen is greater than lthe distance between the edges of the opposing channel-shaped slideways, the greater depth of one slideway enables the screen to be readily placed in position by placing one edge thereof in the deep slidewayand swinging `the opposite edge inwardly towards the opposite shallow slideway to clear the edge thereof. The screen may then be shifted laterally to bring said opposite edge into the shallow slideway.

The framing members y25, which form the side rails of the upper and lower sash B and B1, are of the same cross-sectional size and shape. Each of the members 25 comprises side marginal flanges 26 connected by a web portion. The outer mar 'nal portions of the adjacent side marginal` anges ofthe-upper and lower sashes are offset laterally away from the` parting bead C and are formed with integral undercut bead or rib portions 28 which extend from top to bottom thereof. These undercut ribs or beads have a sliding fit in undercut grooves formed nea 1` one margin of resilient metal weatherstrips 29 whose opposite margins are clamped to t-he jamb members of the window casing by means of the stop strips C. The grooved margins of said weatherstrips are extended in the direction of thejamb members of the window frame to form a ,flangeportion 30, which extends between the adjacent sides of the parting strips and the walls of the grooves provided therefor in said jam'b members. It is noted that this arrangement permits the sashes to be loosely fitted in the window frame while preventing draft and keeping out dust and water,

The framing members 31, which form the top rail of the upper sash and the bottom rail of the lowersash, are of the samecrosssectional size and shape. Each of said members comprises side marginal flan es 32 connected by a. web portion, one o said side marginal flanges bein shorter than the opposite side marginal ange `and terminating in the laterally extended portion 32 which projects toward said opposite flanges. The

lower or meeting rail 33 of the upper sash I B` `comprises 4a framing member of sub-4 stantially inverted channel-shaped section, whose inner marginal flange is provided with an upwardly extending flanged fportionl 34 spaced away from said flange a to accommodate the free end of a resilient metal weatherstrip 35. The top or meeting rail of the lower sash 'B1 comprises a channel-shaped member 36 whose channel is closed by means of a horizontal plate 37 whose inner margin fits in a groove provided therefor in the rear flange ofthe meet.

ing rail. The outernlargin of the plate 37 has a. depending flange 38 which rests on a shouldered portion of flange of the meeting rail and is removably secured thereto by means of screws 39. The weatherstrip 35 is clamped between the depending flange -38 ofthe top plate 39 and a shoulder provided therefor in the front marginal flange of the'meeting rail and is thus adapted to move with the lower sash when the same is raised and lowered. The framing members of the sashes have their web portions offset to form rabbets adapted to accommodate the marginal edges of sash panes 39', said panes being held in place by putty,

in accordance with common pract1ce.

As shown in Fig. 1 of the'drawings, thev 'rendered weather-proof and'dust-proof by means of metal weathers'trips 37. l These metal weatherstrips preferably comprise reversely bowed side marginal flanges 38 connected' by transversely curved or bowed web portions. The strips are adapted to `be sprung in the channels of the framing members 3l and have resilient sealing flanges or tongues 33 adapted to bear-against the adjacent faces of the window frame and thus seal or close the joints therebetween. A great practical advantage of the construction just described is that it minimizes time and expense in applying the weatherstrip by eliminating the necessity of altering the sash or frame and by enabling the strip to be readily applied without the use of separate fastening members.' l

At the corners of the window frames and sash frames, the adjacent ends of the side flanges of the framing members thereof are beveled4 and are disposed with their beveled ends in abuttingrelation. The web at one end of` a framing member overlaps the adjacent r enough the outer marginal` i 41 of the other framing member has a wedge y Figures 3 and 4.

42 extending therethrough in posit-ion to bear against said extension 41, which are also provided with openings adapted to receive wedges 43. By this arranvement, the beveled ends of the frame window frames and sash frames are tightl drawn together to form rigid corners whic i" prevent distortion-of said frames.

It is noted that the manner of assembling the window and sash frame permits shipment of said frames in knocked-down form and enables the frame to be quickly and easily assembled at-the place of use without the difficult and expensive operation of crimping, welding or riveting the parts.

, The window shown in Figures 5 and 6 of the accom anying -drawing 1s of the reversible venti ator type, said window comprisingr a metal window casing or frame A1 having al metal sash B3 mounted .therein for vertical sliding and vertical swinging movement. In this type of window construction, the framing members 10 form the head and both jamb members of the casing A1; and a` separate inverted channel-shaped framing member 44 having a downwardly offset web portion, forms the sill member thereof. The sash B3 is made up of the channel-shape framing members 31, which are secured together in the manner shown in The upper corners of the sash are pivotallyA secured, by meansl of brackets 44', to lblocks 45 that are slidably mounted in the channels 13 of the framing .members 10 ofthe window casing. The

slide blocks 45 are retained in the channels 13 by means of metal strips 46 that are removably secured to the members l10 adjacent to said channels and project across the same. The! weatherstrips 37 are sprung into the channels of the frame members 31 of the sash B3 and thus serve to weatherproof the window.

. The window construction shown in Figures 7 to 9, inclusive, is of the double-casement type and comprises a metal window casing or frame A3 and two vertically pivoted metal sashes BtL pivoted to the jamb members lof 'the window frame by means' of hinges 47. In this type of window construction, the framing members 10 form the head and jamb members of the window casing A3, and the sill memberl 44, shown lin Figure 5, forms the sill member thereof.

n The framing members 31 form the inner,

top and bottom'rails of the sashes B4, and

separate members 48 form the meeting rails thereof. framing members of substantially channelshaped section and are arranged so that their outer flanges overlap in the closed position of the sashes. The outside {iange of one meeting rail is provided with an inwardly extending flange 49, and the inside mem ers of the These meeting rails .comprise It is noted that the ,hereln described ar` rangement permits a maximum number of framing members of the same cross-sectlonso I al size and shape to be used with windows f of different types andreduces to afminimum the number pf specially formed framing members required for each type of window. It also permits windows of diti'erent types to be combined lin the same opening by using side and head framing members of the same cross-section, the shape ofthe sill member depending upon the mannerl of mounting the sashes.

It is also noted that the frame members of the sash and window frames are of such cross-sectional shape that they cannot be v formed by a rolling or pressing operation. However, these members are well suited for production by extrusion. By such process, the metal, which is usually heated to a'.

fairly plastic condition, is forced under high pressure through an aperture of the shape to be produced. By resortingto this extrusion process, parts of unusual cross-section can be produced cheaply. On account of the high pressure under which the metal is extruded, its structure becomes more compact and its strength is increased. The surfaces of said metal are smooth and free-from flaws or other defects. The dimensions of such extruded yshapes can be gaged with great accuracy so that they can be used directly without additional finishing. The use/'of extruded aluminum parts is preferable by reason of their light weight and ltheir resistance to rust and corrosion.
